中国科学院上海细胞生物学研究所副研究员张果,江苏省昆山县人,1911年出生。1930年去北平就读于北平大学农学院生物系,1934年肆业后转至河北农学院学习,后任助理,开始从事生物学教育和研究。1935年9月,张果在北平中法大学生物系任助理期间,开始作为我国著名生物学家朱冼教授的助手,从事实验细胞学方面的研究。 1935年,当朱冼教授以北平郊区的黑斑蛙卵球为实验材料,进行人工单性生殖研究时,张果参加了这一工作。他协助朱冼教授涂血针刺了三千多个黑斑蛙卵球,获得了20个蝌蚪,其中有两只正常变态成无父小蛙。1938年朱冼教授和陈兆熙、张果共同署名,发表了论文《中国蛙类的人工单性生殖及三龄无父蛙的记载》。
Zhang Guo, an associate researcher at Shanghai Institute of Cell Biology, Chinese Academy of Sciences, was born in Kunshan in Jiangsu Province in 1911. In 1930 went to Peking University Peking University College of Agriculture Department of Biology, after 1917, he went to Hebei Agricultural College to learn, after serving as assistant, began to engage in biology education and research. In September 1935, Zhang Guo started his research on experimental cytology as an assistant to Professor Zhu Xian, a famous biologist, during his tenure as a assistant professor of biology at Peking University’s French and Chinese universities. In 1935, Professor Zhang Zhu participated in the artificial parthenogenesis study when Professor Zhu Xian took the black spot frog ova as an experimental material in the suburbs of Peiping. He assisted Prof. Zhu Xian in smearing blood-stained acupuncture on more than 3,000 black spot frog eggs, obtaining 20 tadpoles, of which two normally metamorphosed into fatherless frogs. In 1938, Professor Zhu Xian and Chen Zhaoxi and Zhang Guo co-authored the paper entitled “Artificial Parthenogenesis of Chinese Frogs and Record of No-frog in the 3rd Age”.
